It appears that there may have been some issues with the firmware for folks who need access to some of the advanced features of the Obi. I have been using 1.3 for about 1 1/2 months now and all of the issues that I was having trouble with are working, but I am using a "plain vanilla" set up so I am happy with it. I suspect the reason it was pulled revolves around the fact that once it is installed, you can't go back to v1.2. They may have decided to hold off installing it until they could decipher some of the reported bugs.
